Why remove the prepared statements from cache?

[domoritz]

Maybe I am misunderstanding the logic here but I wonder why duckdb removes the statement from the cache instead of just getting it? I would expect a call to https://paritytech.github.io/try-runtime-cli/hashlink/lru_cache/struct.LruCache.html#method.get.
